No connection to MQTT Broker possible

[stundenblume]

After some trouble I got the basic and callback examples running successfully.

But if I try to connect to a unsecured Mosquitto broker it won't connect.

Opened the MQTT example and modified it to:

#define SLEEP_EN        false

and

#ifndef SECRETS
    const char ssid[] = "xxxxxxxx";
    const char pass[] = "yyyyyyyy";

    #define HOSTNAME "ESPWeather"
    #define APPEND_CHIP_ID

    #define    MQTT_PORT     1883 // checked by pre-processor!
    const char MQTT_HOST[] = "192.168.123.186";
    const char MQTT_USER[] = ""; // leave blank if no credentials used
    const char MQTT_PASS[] = ""; // leave blank if no credentials used

After compiling and uploading, I get this massage:

I tried two simple sketches to verify a connection to the broker is possible. This very simple code also won't connect.

But this code runs as expected.

Maybe this issue is related? I will try to find out why no connection to the broker is established.

After changing this:

//#define USE_SECUREWIFI          // use secure WIFI
#define USE_WIFI              // use non-secure WIFI

everything works as expected.
